Press Release

CUPERTINO, Calif. - May 13, 2003 - Symantec (Nasdaq: SYMC), the world leader in Internet security, today announced Norton Internet Security 3.0 for Macintosh, the world's most complete Internet security solution for the Macintosh platform. The latest version of the market-leading software suite, which is scheduled to be widely available in June, will now include a new parental control feature that blocks Web sites that are inappropriate for viewing by children. Norton Internet Security 3.0 for Macintosh will also include the newest version of Norton AntiVirus 9.0 for Macintosh, which now will have the ability to find and repair Windows/PC-compatible viruses, offering users protection from the most common type of viruses and helping them to avoid infecting friends and colleagues.

"With so many Mac users capitalizing on the recent explosion of Internet technology, Symantec's goal is to help those users minimize the risk factors that could compromise personal safety and security online," said Steve Cullen, senior vice president of Symantec Consumer and Client Product Delivery. "With Norton Internet Security 3.0 for Macintosh, Mac users will be able to do everything - from downloading music files to sharing digital photographs and shopping online - all with the peace of mind that comes with the kind of reliable protection that only Symantec can deliver."

"Our customers' security and the health of their systems are extremely important to Apple," said Ron Okamoto, Apple's vice president of Worldwide Developer Relations. "We're excited that Symantec's new release for Mac OS X will add to the security and safety of our users and their systems."

Expanded Privacy Control
Norton Internet Security 3.0 for Macintosh includes Norton Privacy Control, providing Internet users with important tools to protect their personal information and to improve their Web surfing experiences. With the addition of new Parental Controls, Mac users will be able to limit access to illicit Web sites when their kids go online. Parents can either create their own list of inappropriate sites to block, or they can download a URL list produced and maintained by Symantec. This URL list will be updated regularly to keep up with the latest questionable Web content, and will automatically be provided to Norton Internet Security users via Symantec's LiveUpdate technology.

Norton Privacy Control also offers users new advanced ad blocking capabilities, which now will prevent more types of Web-based advertising delivery, including JavaScript, allowing Mac users to access the Internet with less hassle from the constant intrusion of unwanted banner ads and pop-up windows. Additionally Norton Privacy Control has enhanced confidential data blocking to help users avoid unknowingly or accidentally sending out sensitive information online, including via Instant Messenger programs.

Complete Protection from All Types of Viruses
Adding the ability to scan and disinfect PC viruses, Norton AntiVirus 9.0 for Macintosh will now protect users from passing along the most common types of computer viruses, as well as worms and Trojans. In addition to protecting users from Mac-specific threats, the latest version of Norton AntiVirus for Mac will also prevent Mac users from inadvertently being carriers of Windows-based threats and proliferating malicious attacks. PC virus, worm and Trojan protection also will enable multi-platform users to utilize one solution to protect all their operating systems from the threat of attack.

New functionality in Norton AntiVirus 9.0 for Macintosh will also include the ability to quarantine "unrepairable" virus-infected files, and allow users to scan and repair compressed Mac files. Symantec has also enhanced LiveUpdate, helping users to dramatically reduce the time it takes to download new virus definitions.

Firewall Protection Made Easy
Norton Personal Firewall 3.0 for Macintosh will help keep Mac users' data safe and secure by providing a protective layer between their computers and the growing number of hackers and intruders that lurk online. With the latest version, Symantec adds a new Set-up Assistant to ensure easy installation and configuration. It will also help users by detecting services, such as file-sharing, when they are activated to prevent potential conflicts. Additionally, it will provide a higher level of security by blocking both inbound and outbound connections, and also allows users to identify and trace potential hacking attempts in real time with the new Visual Tracking feature.
